[Interface type helmet non-invasive mechanical ventilation]

Non-invasive mechanical ventilation is a technique that has ceased to be exclusively used in intensive medicine services to form part of the armamentarium of emergency and critical services, assuming an adaptation to this procedure by the nursing staff whose participation is crucial to achieve the triumph of technique. Composed basically of a mechanical ventilator and a mask (interface) which is interposed between the patient and the fan without invading the airway, requires the collaboration of the patient unlike conventional mechanical ventilation and, initially, a longer time of dedication of the nurse. Interfaces models and the evolution of the same to achieve the effects desired with good tolerance by the patient came to the development of the Helmet, a device in the form of diving, well tolerated by the patient, allowing the use of high pressure for alveolar recruitment, but that, by design, has connotations that must be known before use.
